Yes. In about 5 billion years it will stop fusing hydrogen in its core. This is considered the end of its life due how small Sun is. After this it will become a red giant, experience a helium flash, fuse helium rapidly, shrink down, get a lot bigger, and will not be able to hold on to its own mass anymore, so it will release it gradually to form a planetary nebula around it, and it will become a white dwarf. After this, it's life is pretty boring.
